Fixed lakes elevation
...
There were sometimes missing water patches near a lake's edge, when the neighbour catchment area was lower.
This commit allows to divide a cell into several mini-catchment basins, to fill only a part of it with water.

For noise map seed: don't go over ±4096, to prevent rounding errors on coordinates (because noise library uses 32-bit floats)

Lakes map: keep initial height (reduces file size)
...
Lake height is calculated for every basin, and there is a lake if lake height is higher than ground height. If it is lower, there is no lake.
In that case, it was previously raised to ground level, but since this can be done in Lua, we can write initial lakes height in the files.
This has the advantage of reducing file size, since there are bigger areas of equal values, that are more efficiently compressed.

Protect map preview from exceptions

Since map preview is optional, an exception should not propagate to terrain calculation, so print an error message + traceback but keep the script running.

Horizontal shifting according to 3D noises:
...
makes slopes more irregular and natural-looking, allows overhanging.
This is done by generating an intermediate 2D elevation map and, for each node in 3D, add a 2D offset vector to the position, and seek this position on the heightmap.
